Specification of Letters Patent.

Patented. May 11, 1909.

Application filed February 8, 1908. Serial No. 414,967.

To all whom it may concern:

Be it known that merchant, a subject of the Emperor of Austria-Hungary, residing in Urfahr, Austria- Hungary, have invented certain new and useful Improvements in Numbering-Hammers, of which the following is a specification.

numbering devices and has for its object the provision of a numbering hammer adapted for use in opening and closing boxes and provided with numbering means convenient for use in numbering boxes when they have been handled prior to or subsequent to shipment. The device-of my invention is also adapted for other uses wherein a numbering device would be serviceable in connection with a hammer. T

One of the objects of my invention. is the provision of a pluralityof numbering members which may be in the form of type disks, and which are disposed or associated with the hammer and provided with means whereby they may be shifted or advanced to change the position thereof.

the provision of a single shifting oradjust- 111 teiis disk after the units disk has been shifted ten times.

ings and which will be more particularly pointed out and ascertained in and by the appended claims.

In the drawings :--Figure 1 is a sectional view on line 1 -1 of Fig. 3. Fig. 2 is a bottom plan view looking in the direction of arrow 2 of Fig. 1 with parts of the handle removed. Fig. 3 is a sideelevation, with the handle removed and'partsbroken away to show internal mechanism in section. Fig. 4 is a sectionalview, similar to Fig. 1, showing a modified construction. Fig. 5 is a plan view with parts broken off. Fig. 6 is a sectional view on line 6-6 of Fig. 3.

I, FRANZ PRoLL, wood This invention relates to improvements in hammer is indicated poll 34, a face 35 and apeen 36, the latter the hammer numbering hammer 'firim. or company in device for automatically shifting the i Numb lar parts throughout the different figures of the drawings.

Referring to Figs. 1, 2, 3, 6 and 7, a

at 4 and comprises a of which may be of any desired form. If is desired foruse wholly as a the face 25 may have a suitable typed designation, at,6 for example," which may indicate the V whose place of business the hammer is'being used. The peen may be advantageously used in prying open the boards of boxes or in a like capacity. The

poll 34; of the hammer is provided with an opening and the samemay consist of 'a transverse passage 37 .formed in a manner to. provide upper andlower walls and also side walls so that the passage is entirely in- E 1 closed except at opposite sides of the ham- A feature of this improvement consists in mer. The hammer 4 is bored at right angles to its longitudinal axis to receive a handle rod 1 and the hammer is conveniently provided with asleeve extension 8 provided with notches 24.. A handle 3 is disposed on A further novel feature of the invention consists in associating the numbering .mem-

said rod 1 and the latter is provided with a member in the form of a disk 2 having projections or pins 28 which engage the notches 24 and also having a polygonal portion extending into the handle 3. Thumb nuts (one being shown) are provided on the opposite ends of the rod 1 so that it will be seen that when the thumb nuts are turned down means are provided for non-rotatively locking the hammer, rod and handle with respect to each other.

ering members preferably in the formof type disks are disposed in the opening or passageway 37 in a manner to project outwardly therefrom and as shown two disks are provided, one designated at 9 being the units disk and the other designated at 10 being the tens disk. The peripheral portions of the units and tens disks are preferably flattened to afford a surface on which to dispose the type and said disks are bored to permit passage of the handle rod 1 therethrough. The handle rod 1 serves to maintain the disks 9 and 10 in concentric rela tion with respect to each other but in adas indicated said teeth are circularly disposed about the .19 provided with aniextension '19 project bees in the upper wall of the passageway 37 gage annular teeth 11 formed on the lower ing or adjusting the type disks step by step .tion which is hollow and adapted to re- .25 isadapted for engagement with an .openother end .of the spring 25 encircles theexmounted in a manner to lie in parallel relamember 17 is preferably in the form of a aXis of the disk 10 and are radially arranged with respect thereto. In the opposite face of the disk 10 a "locking groove 39 is conveniently provided and a locking d-etent ing into said groove may serve as a convenient means for preventing backward movement of the disk '10 and permitting forward movement of the rotation there- The locking .member or detent 19 may be in the form of a spring and may be ,convenientlyiseated .in a shallow .re-

as clearly shown in 'Fig. A similar retaining device 19 may .beseated in a similar recess in the lower wall of the passageway37 and its projection 19 may conveniently ensurface of the disk 9 as clearly shown in 'Figs. 1 and 8. An opening ,12 is formed in the disk 9 which may intersect portions ofthe teeth 11, and consequently .oneof-the teeth 11 relatively shorter than the remaining teet I will next describe the means for shifta distance equal to one of the teeth or one of the flat peripheral surfaces thereof.

A rotatable member 18 surrounds the sleeve 8 and engages the lower face of the hammer and the upper face of the annular plate .2. Said rotatable member 18 is provided with an enlarged annular upper porcelive a spring .25. One .end .of said spring ing 31 .in the rotatable member 18 ,and the tension sleeve 8 and is secured in a recess in the bottom surface .of the hammer 4, as clearly shown in Figs. 1, 2 and The spring 25 servesto automatically return the member 18 to a starting position after it has been advanced beyond such position. The rotatable member 18 is provided with .a cylindrical extension .29 in which a shifting or adjusting member 17 is reciprocally tion with the'liandle rod 1. Said shifting rod and is disposed in a manner so that its upper chamfered lend engages the teeth 11. Said .rod 1.7 extends through :a slot 30 in the hammer l 1. and 4t) and carries a collar 4:0, between which and a portion 41 a spring 15 is disposed, by means of which the rod 17 is actuated so that it will normally engage the teeth 11.. The lower reduced end 11 of the cylindrical extension 29 is provided with a slot 1-2 through which a'pin projects so that the rod 17 can be manually withdrawn or depressed for the purpose which will hereinafter more fully appear.

It will be obvious from the foregoing that after the user has struckan imprinting blow with the numbering hammer he may engage the ,-ylindrical extension 29 with his thumb and shift or rotate it about the rod 1 a center until the rod 17 engages the right hand end of the slot 30, whereupon theshifting movement of the rod 17 and extension 29 and member 18 will be arrested and if the parts are released the spring 25 will. return them to a normal or startin position with the rod 1.7 at the left handeiu of the slot .30. At each shifting or adjusting movement of the rod 17 the latter will engage the teeth 1.1 on the disk 9 and rotate the disk a distance equal in length to the length of one of the flat peripheral surfaces thereof and will rotate another type into alinementwith the type of the tens disk 1.0. Then the shifting device has been successively moved to adjust the units disk 9 .step by step, from 1 to 10 it will then be necessary to shift the tens disk 10 one step to bring the next higher numeral thereof into alinement with the type of the units disk which is in a printing position. The shifting rod performs this function by projecting through the opening 12 in the units disk 9 when it attains a position of-registry therewith and the spring 15 instantly raises the member 17 through the disk 9 into engagement with the teeth 38 of the tens wheel. It will thus be seen that subsequent movement of the member 17 will shift both the units and tens disks 9 and 10 respectively one step and when such movement has been completed .and arrested by the slot 30 the operator will depress the member 17 by engaging the pin 13 so that when the spring 25 returns the rod 17 to a starting position the same will reengage the teeth of the units wheel 9.

Hundreds and thousands suflix type me1nbers 20 and 22 are mounted upon the rod 1 and are held in place by the upper thumb screw thereon. The sufiix type member 20 is provided with a segment 21 engaging the periphery of the poll of the hammer and is slotted at 5 and provided with recessed slot terminals 33. The suiiiX member 22 is also slotted at 32 and is provided with a recessed upper portion 33 to receive a washer 33". It will be seen that in view of the fact that the recess 33 is slotted a width narrower than its diameter that the washer 33 will be efiectively held in the recess 33' by the upper weight nut and the parts 20 and 22 will be securely anchored in place.

I claim 1. A numbering hammer comprising in combination with a hammer provided with an opening, of type disks rotatably mounted in said opening and projecting therefrom, one of said disks having an opening therethrough, a handle for said hammer, and a single shifting member cooperating with one of said disks through said disk opening and serving to independently shift another of said disks.

2. A numbering hammer comprising in combination with ahammer having an opening, of type disks rotatably mounted in said opening and projecting laterally therefrom,

both of said type disks having teeth and one of said type disks having an opening therethrough, a handle for said hammer, a rotatable member mounted on said hammer and provided with a single shifting member cooperating with the teeth of one of said disks directly and engaging the other of said disks by projecting through said disk opening, and means for returning said rotatable member to a startin position.

In testimony whereof I ax my signature in presence of two witnesses.
